A 135-square-meter "zero energy emissions and zero carbon" building in the China-Singapore Tianjin Eco-City made headlines in domestic media outlets recently.

The innovative space, a collaborative research project by State Grid Tianjin Electric Power Co, is fitted with 60 solar panels capable of generating over 20,000 kilowatt-hours of electricity annually.

This translates to saving approximately 8 metric tons of standard coal per year or reducing annual carbon dioxide emissions by around 20 tons.

The building features a 40-kWh energy storage battery that, in energy-saving mode, can sustain the building's energy requirements for nearly two days.

Intelligent energy control facilitated by the energy router in the building allows for efficient energy transmission between the grid, solar panels, energy storage and household appliances.

This pioneering space is just one example of the eco-friendly initiatives in the eco-city.
